Well, my experience of people who have come to the UK is that they are young, fit and vigorous. They don't put much pressure on the NHS because they are net contributors, tax-wise, and they take very little out as a result of it. Let me give him an example of health tourism: the doctors who work in our NHS, the nurses, the physiotherapists, the medical staff—all of whom have come to Britain to work within the national health service. The national health service could not exist—could not exist—without being able to access the medical expertise of doctors, nurses and others from other countries. Yes, I think health tourism is a good thing because it makes sure our people stay well and alive.
